public class CarCollector extends Application {
private final String SCRIPT
= getClass().getResource("carCollector.js").getPath();
public static void main(String args[]) {
launch(args);
}
@Override
public void start(Stage stage) {
try {
ScriptEngine engine = new
ScriptEngineManager().getEngineByName("nashorn");
engine.put("primaryStage", stage);
engine.eval(new FileReader(SCRIPT));
} catch (Exception e) {
e.printStackTrace();
}
}
}

carCollector.js
, which
implements the application. Note that the code does not contain a
start()
function,
because the application
start()
method is already implemented in the Java code.
The JavaScript file merely contains the implementation.
